Abstract

A full enclosed forging apparatus comprising a construction in which an upper die holder (1) and a lower die holder (2) are respectively disposed as to face a press machine, at least one of the upper die holder (1) and the lower die holder (2) is composed of a holder main body (4a) or (4b) holding a die (3a) or (3b) and a holder base (5a) or (5b) attached to the press machine, and the holder main body (4a) or (4b) is attached to the holder base (5a) or (5b) through plural spring mechanisms (20) with an aperture (C) as an interference of the spring mechanisms (20) as that an upper punch (9) proceeds into the die (3a) and a lower punch (10) proceeds into the die (3b) after the upper die (3a) held by the upper die holder (1) and the lower die (3b) held by the lower die holder (2) contact.
